Product Details

Description:

This dredger is non-self-propelled, chain bucket type gold mining dredger, the hull adopts the assembly type box structure.It is equipped with a bridge hoisting device, a five anchor positioning device and a chain bucket device, screening device, gravity separation equipment, and tail transport equipment, etc. The chain bucket is driven by the decelerating engine of the motor.The generator set provides all electric power, lighting and other electricity on the dredger. The forward winch, the bridge winch are all driven by the reducer.

Because of heavy sand (black sand) content more than 15%, so adopt the following technology:

Step 1: it is recommended that a water jet centrifuge is used for enrichment, which is expected to enrich about 90% of heavy metals.

Step 2: The tail of the enrichment is added to the secondary enrichment of the sluice box. Since most of the heavy metal has already been enriched by the centrifuge, the sluice box can be cleaned 1-2 times a day.

Product Features:
1. The dredger could be divided into bucket type and pump suction type. Bucket type dredger is applied for waterways with high percentage of clay and gravels, while pump suction type can only be used for terrains with low percentage of clay and gravel.
2. Customized according to specific requirements for dredging depth and capacity.
3. Iron ore needs to be retrieved first with magnetic separator if the percentage is high in the raw ore, then gold, diamond, zirconium will be concentrated.
4. The dredger is composed of several gravity concentrators. The concentration ratio could reach as high as 1:1000, and the recovery efficiency about 90% after series of separator.
